Abstract/Summary

In this document, we describe and evaluate the four-day week pilot project in Portugal. The report is divided into four parts that can be read independently. The first part describes the origin, definition, and development of the project. The second part details how companies implement the four-day week and how they appraise it. The third part evaluates the effects of the reduced working hours on workers. The fourth part proposes three stages to be followed in the future.
